Aircraft Rockets

Article excerpt

The Aviation Rockets and Missiles (ARM) Project Office, under the PEO Tactical Missiles, was formed in August 2000 with the merger of the 2.75-inch Rocket Systems Project Office and the Air-toGround Missile Systems Project Office. The ARM Project Office manages the 70 mm rocket (formerly the 2.75-inch rocket), all variants of the Hellfire missile, and the advanced precision kill weapon system (APKWS).

The 2.75-inch (70 mm) Hydra 70 Rocket Family encompasses variants of the freeflight rocket that has become the standard ground-attack rocket. The design includes multiple warheads that can be used on the rocket motor.

Equipped with various fuzes, warhead options and target sets include: M261 tactical; M267 practice; M151 (10 pound) anti- ι personnel or canopy/soft bunker; M229 anti-personnel (17 pound); M274 smoke signature; M257 illumination; M264 smoke; M255A1 fléchette; and M278 infrared illuminating.

The Hydra 70 was used extensively in the Korean War, Vietnam War and Operation Desert Storm. It is a conventional ammunition item used by all U.S. services ; and many foreign countries. Both the 70 mm rockets and the Hellfire missiles are the primary armament for the U.S. Army's AH-64 Apache, OH-58D Kiowa Warrior and the U.S. Marine Corps' AH-IW Super Cobra helicopters.

Hydra program funding continues in FY 2003-06 to support transitioning technology to the Advanced Precision-Kill Weapon System (APKWS).

APKWS is currently in development and will provide a guided, low-cost, lightweight weapon that is effective against soft and lightly armored targets to fill the gap between the 70 mm rocket and the Hellfire missile. The system will be used by all Army aircraft currently using the 70 mm rocket. …
